AWS bill analysis pipeline explains cost changes and hidden infrastructure issues

A developer built a custom pipeline to create monthly AWS reports that link cost changes to operational decisions.

It uses a simple stack of Bash, AWS CLI, Python, JSON, HTML, and PDF, with AI assistance only for commentary generation. The goal is to automate factual data collection while keeping human analysts responsible for final conclusions. The three-layer system separates data collection, interpretation, and presentation to prevent assumptions from being treated as certainty.
